free ends of both the stringing pins and the suspension tubes tend tomove downwardly, thereby considerably facilitating the removal of adrawing and contributing to careful handling of all the drawings, whichon the front of the cabinet being opened automatically loosen andseparate from one another owing to the inclined position of thesuspension elements.

For the purpose of facilitating the Stringing of the drawings or plansto be filed onto the suspension tubes, the latter are bevelled at theirfree ends, while the free ends of the Stringing pins are rounded, so asto ensure easy introduction of said pins into the suspension tubes 6.

In order to enable the front wall 3 of the cabinet to be arrested inseveral different positions,

for example, two, stop means are arranged on both sides of the cabinet.These stop means consist of two locating rails 9 articulated one ateither side of the tiltable front wall 3, each of said rails being atits free end provided with a bent lug l2 and, at a certain distanceinwardly therefrom, with a notch I0. These locating rails cooperate withguide members I I attached to the inner faces of the side walls in suchmanner that the front can be arrested in two positions, one

' being that in which the notches I0 in the locating rails co-operatewith the guide members Il, and the other being that in which the bentlugs I2 of the locating rails 9 abut against the guide members Il tohold the front wall 3 firmly. In the latter position of the front Wall 3the Stringing pins 5 are out of engagement with the suspension tubes G,so that a space is provided between the free ends of said tubes and pinsfor the insertion or removal of the drawings.

Alternatively, other locating means such, for example, as simple chainsmay beused.

The drawings or plans I1 (Figure 4) to be filed in the cabinet may beprovided with a suitable reinforcement which prevents the perforationstherein being torn, being preferably attached to a strip I8 providedwith perforations, `which strip is composed of somewhat stii paper orsimilar material. The suspension tubes and the stringing pins engagesaid perforations of the said suspending strip. The plans are preferablyattached to the suspending strip by means of a strip provided with anadhesive. The suspending strips I8 prevent damage to the perforations inthe drawings and need not be removed until the drawings are required forthe preparation of prints by means, for example, of mechanical copyingapparatus.

The suspending strips I8 may if desired be provided with any desiredlegend for the purpose of facilitating easy and orderly filing of theplans.

Upon the inner face of the top i there is preferably arranged a table ofcontents (not shown) which gives a ready review of all the drawings andplans filed in the cabinet, so that any drawing 'and its serial numbercan at once be found.

What I claim and desire to secure by Letters Patent of the United Statesis:

1. Filing cabinet for drawings, plans and the like having a rear wallmember and a tiltable front wall member, means on which, said drawingsare suspended in the cabinet comprising straight tubular suspensionelements pivotally attached for vertical swinging movement to the rearwall member, and straight stringing pins pivotally attached also for`vertical swinging movement to the front wall member, said suspension'elements and Stringing pins telescoping to form a rigid support forlthedrawings in the will again telescope. l

2. Filing cabinet for drawings, plans and the like having a rear wallmember and a tiltable front wall member, means on which said drawingsare suspended in the cabinet comprising straight tubular suspensionelements pivotally attached 1 for vertical swinging movement to the rearwall member, and straight Stringing pins pivotally attached also forvertical swinging movement tc the front wall member, said suspensionelements and Stringing pins telescoping to form a rigid sup- 2 port forthe drawings in the closed position of the front wall member anddisengaging from one another in the fully open position of said frontwall member, and hinge means connecting the lower portion of the frontwall member to the 2 cabinet so that upon said front wall member beingswung open on said hinge means the pivotal mountings of the Stringingpins on said front Wall member will progressively swing downwardly so asto lower the outer ends of the suspension 3 element and Stringing pinassemblages to inclined positions in which said drawings will tend toslide forwardly thereon toward the front wall member by the force ofgravity.

3. Filing cabinet for drawings', plans and the like having a rear wallmember and a tiltable front Wall member, means on which said drawingsare suspended in the cabinet comprising straight tubular suspensionelements pivotally attached for vertical swinging movement to the 4 rearwall member, and straight Stringing pins pivotally attached also forvertical swinging movement to the front wall member, said suspensionelements and Stringing pins telesccping to form a rigid support for thedrawings in the closed position ofthe front wall member and disengagingfrom one another in the fully open position of said front wall member,positioning means on said rear and front wall members limiting both thesuspension elements and Stringing pins to mutually registering positionsin the disengaged position thereof, so that when the front wall memberis swung toward the rear wall member said suspension elements andStringing pins will again telescope, and hinge means connecting thelower portion of the front wall member to the cabinet so that upon saidfront wall member being swung open on said hinge means the pivotalmountings of the Stringing pins on said front wall member willprogressively swing downwardly so as to lower the outer ends of thesuspension element and Stringing pin assemblages to inclined positionsin which said drawings will tend to slide forwardly thereon toward thefront wall member by the force of gravity.

4. Filing cabinet for drawings, plans and the like having a rear wallmember and a tlltable front wall member, means on which said drawingsare suspended in the cabinet comprising straight tubular suspensionelemeng pivotally attached for vertical swinging movement to the rearwall member, and straight Stringing pins pivotally attached 4also forvertical swinging movement to the front wall member, said suspensionelements and Stringing pins telescoping l ment of said suspensionelements and string' ing pins to mutually registering positions in thedisengaged position thereof, so that when the front wall member is swungtoward-the rear wall member said suspension elements and stringing pinswill again telescope.

5. Filing cabinet for drawings, plans and the like having a rear wallmember and a tiltable front Wall member, means on which said drawingsare suspended in the cabinet comprising straight tubular suspensionelements pivotally attached for vertical swinging movement to the rearwall member, and straight Stringing pinsy pivotally attached also forvertical swinging movement to the-front Wall member, said suspensionelements and Stringing pins telescoping to form a rigid support for thedrawings in the closed position of the front wall member and disengagingfrom one another in the fully open position of said front wall member,positioning means on said rear and fro'nt wall members limiting both thesuspension elements and stringing pins to mutually registering positionsin the disengaged position thereof, so that when the front wall memberis swung toward the rear wall member said suspension elements andStringing pins will again telescope, guide members attached tov the sidewall members of the cabinet and locating rails pivotally attached tosaid front wall member and cooperating with said guide members to arrestthe front wall-member at the fully open position and intermediate thefully open position and the closed position of said front Wall member inorder to determine variously extended telescoped positions of the pinsand tubular members and corresponding swung positions of the front wallmember including a fully open position' thereof, in which the pins arespaced from the-tubular members providing a gap between their adjacentends for removal of individual drawings suspended on the suspensionmeans, said locating rails being formed with lugs at their free ends andnotches inwardly of said lugs adapted to engage said guide members.
